EDWARD SUTTON, OF BROOKLYN, NEW YORK.

FIRE-ESCAPE.

SPECIFICATION forming part of Letters Patent No. 369,137, dated Augustso, 1887.

Application filed May 5, 1887. Serial No. 237,215. (No model.) 7

To all whom) it may concern."

Be it known that I, EDWARD SUTTON, of Brooklyn, in the county of Kingsand State of New York, have invented anew and Improved Fire-Escape, ofwhich the following is a full, clear, and exact description.

Reference is'to be had to theaccompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of my invention applied to a ladder. Fig. 2is a front elevation of the same. Fig. 3 is aplan view of thefire-escape without the ladder. Fig. 4 is an enlarged sectionalelevation taken on the line as x of Fig. 3. Fig. 5 is an enlarged detailside view of the winding-drum, and Fig. 6 is a sectional plan view ofthe upper end of the ladder.

The invention will first bedescribed in connection with the drawings,and then pointed out in the claims.

A A represent the side pieces of the main frame (if the fireescape.These side pieces are of cast-iron joined together by the rods B B, andin these side pieces is journaled the shaft 0, on which is secured thebrake-drum D and the ratchet-wheel E. At the sides and base of the sidepieces, A, are cast the cleats a a, which receive the lower ends of theladder F, and hence the frame of the fire-escape becomes the support forthe ladder, as will be understood from Figs. 1 and 2, the bottoms of theside pieces, A, being flanged, as shown at a a, for supporting theladder.

Upon the shaft 0, between the brake-drum D and the ratchetwheel E, isplaced loosely the drum G, upon which is wound the rope H. This ropereaches from the drum G up over the pulley J, placed upon the rod K,attached to the top of the ladder F. Upon the drum G isplaced anotherrope, L. This is wound in the opposite direction from the rope H, sothat when the rope H is paid out the rope L will be wound up, and viceversa. Over the drum D is placed the strap M, which is attached at oneend to the pin b in one of the side pieces, A, of the frame, and at theother to the lever N outside of the fulcrum c of said lever, so thatwhen said lever is pressed downward the strap M will be drawn in firmcontact with the drum D, andthus act as a brake to prevent the rope Hfrom passing out too rapidly. Another strap, M, is attached at one endto the pin b, and at the other to the lower end of the lever N, so thatwhen the said lever is depressed at its outer end it will alsobring thestrap M into contact with the drum D, so that with a single lever bothstraps M M may be held in contact with the drum D, which constitutes avery efiectual brake. When any weight comes upon the rope H-that of aperson, for'example, descending from a burning building-the drum G willbe lockedv to the shaft 0 by the click 0, engaging with theratchet-wheel E, so that the weight will cause the said drum, the shaft0, and the drum D to revolve, all of which may be easily controlled bythe lever N. The unwinding of the rope H from the drum G will wind therope L on the drum G, so that by simply pulling upon the rope L therevolution of the drum G may be reversed for quickly winding up the ropeH.

The rod K is attached to the ladder by the cleats k k, which aredivided, as shown at k, to enter recesses k", made in the uprights ofthe ladder, so that by simply slipping the cleats in place and placingthe ladder upon the frame of the fire-escape, and passing the rope Hover the pulley J, all will be in readiness for the firemen to ascendthe ladder and lower persons by the rope H, the fire-escape beingoperated by persons at the foot of the ladder.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent-- 1. The fire escape herein shown anddescribed, the same consisting of the frame A, provided with the cleatsa, the ladder held by the said main frame and cleats, rods K, pulley J,shaft 0. drum D, secured upon theshaft, the drum G, loose upon theshaft, the ratchetwheel E, click 0, ropes H L, brake-belt M, andbrake-lever N, substantially as described.

2. The rod K, having the slotted keepers k k, secured at its ends andprovided with the pulley J, in combination with the uprights of theladder, cutaway at k to receive the keepers k, substantially asdescribed.

EDWARD SUTTON.
